[0003] The positioning is determined by expulsion from a reference position with a scale (a tape measure), and nails, black ink, and water lines are applied to the water line at that position. There was almost no indication of what position was set at the position determined above the water. Also, in the case of display, the display is handwritten, and the Mizuki is usually used many times with the previous display being written.

[0004] As described above, in the conventional foundation construction, there is almost no jig for positioning on the water pier, and an anchor bolt positioning jig which is installed on a form after the position is determined is a special feature. This is the degree described in Japanese Patent Publication No. Hei 6-94672.

[0005]

However, in the above-mentioned prior art, since the position is determined on the water through by expulsion from the reference position on a scale, it is easy to cause a measurement error in dimensions. However, there is a problem that the positional accuracy of the anchor bolts and the like is reduced.

In addition, since nailing was performed at that position while measuring with a scale, in order to nail at an accurate position, it was necessary to do it carefully.
Approximately 60 nails had to be hammered in a 0 m ² house, which led to a problem of an increase in the number of construction steps.

[0007] In addition, when no position is displayed or displayed at a position determined on the water line, the display is handwritten and the water line is used many times. Therefore, there is a problem that the indications are easily overlapped and it is easy to misunderstand, and a wrong hooking of the water thread occurs, which causes a defect in dimensional accuracy of the foundation.

The present invention solves the above-mentioned problems of the prior art,
